CHARLES-J. PILLIOD, OF TOLEDO, OHIO.

INTERNAL-COMBUSTION ENGINE.

To all whomzit may concern Be it known that I, CHARLES J. PILLIOD, a citizen of the UnitedStates of America, residing at Toledo, in the county 'of Lucas and State of Ohio, have invented certain new'and useful Improvements in Internal- Combustion Engines, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to internal combustion engines, and has for its object the obtaining of a construction of balanced valve, which is completely protectedfrom the excessive internal heat, and which is a construction that can be readily manufactured and is efficient in its operation.

With these objects in view comprises the construction as hereinafter set forth. a

In the drawings: Figure 1 is a longitudinal section through the engine cylinder'and valve case; Fig. 2 is a cross section thereof;

and Fig. 3 is a section on line a:-m Lb y haust ports A is the engine cylinder surroun the usual water jacket B.

C is a cylindrical valve case having its 1 axis arranged parallel to the'axis of the cylinder and preferably formed integral therewith, said case being also provided'with a surrounding water jacket D. v

.E is a etachable central core member within the case 0, which is centrally provided with a combustion chamber-F communicatin with the. combustion chamber within the cylinder Athrough registering ports G and G. Surrounding this combustion chamber F and between the same and the outer wall of the core is a water jacket H, which communicates with the outer water jacket through registering ports I and I.

J is a hollow cylindrical valve arranged in the space between the core member E and the valve case C, and which as shown is of the longitudinally reciprocatory type. There is also as shown a second cylindrical .valve J for cooperation with the valve J together therewith controlling inlet and ex- K and K on opposite sides of the case. The water chambers which are adjacent to the walls of the core and the cylindrical case C completely protect the same from the internal heat of the engine, while the valve J and J are also protected by the water-cooled walls throughout their entire extent. Consequently difficulties in lubrication are avoided as well as any warping or Specification of Letters Patent these packings the the invention 'water jacket of water chamber, valve intermediate said core and outer valve Patented Apr. 11, 1916.

distortion which might result from excess1ve heat.

It is desirable to employ piston rings in connection with the reciprocatin sleeve valves, and I have therefore provi ed a series of rings L L, etc. To facilitate the manufacture these rings are all placed in grooves in the detachable core section E, and-may therefore be assembled before this section is placed within the valve case. To prevent leakage from the ports crossing the joint between the outer casing and the core a series of annular packings are provided, and to insure the permanence of core and outer case are stepped to form shoulders M M M The shoulders M and M are upon. op-

posite sides of the ports G and G, which connect the combustion chamber in the cylinder with the combustion chamber within the hollow core. The packings' M and M are upon opposite sides of the ports I I which connect the outer water jacket W111i] the water chamber within. the core.

Thus boththe leakage of the gases of combustion and the cooling water is prevented. The spark plug N is preferably arranged in the core member E, so that ignition takes place within the chamber F. There is also preferably provided a priming cup 0 which" communicates with the chamber F.

In operation, the valves J J are operated in properly timed sequence by any suitable mechanism, such as pit-man connections P- 'engaging a crank shown). .Durmg the1r or eccentric shaft (not operation the valves are completely protected by the water chambers in the inner core of the outer jacket, so

that there is no danger of carbonization of the lubricant. I

What I claim as my invention is 1. In aninternal combustion engine, the combination with the 'cylinder,'of a cylindrical valve case arranged substantially parallel thereto, inter-connected surrounding water jackets for said cylinder and valve case, a core section detaichably engaging said valve case, comprisin an inner com-v bustion chamber, a surroun ing water jacket and ports establishing communication respectively between said combustion chamber and the engine cylinder and between the the core and the external and a cylindrical sleeve case controlling ports therein.

2.' In'an internal combustion engine, the combination with a cylinder,

of a cylindrical valve case at the side thereof, a water jacket ,7 jacket respectively with jacket, and an annular packing in the joint forsaid cylider and valve case, a detachable cyllndrlcal core within said valve case having a central combustion chamber, a surrounding Water acket and ports for connecting said combustion chamber-and water the vcombustion chamber of the cylinder and external water between the core and valve case for pre-' within said valve case venting leakage from said 3.
